Someone called asking, "how do I figure out what state plane zone I'm in?". I directed them the ArcGIS website where this map comes up. It would be handy if there was some functionality in HYPACK similar to "select on map" that is available for UTM zone, for the State Plane zones as well.
These maps are available in decent resolution from NOAA. It minimum it'd be easy to embed these into geodesy for quick look ups.
